“…An alternative to these conventional fertilizers is the use of organic fertilizers derived from plant and animal byproducts such as seaweed extract, manure or hydrolyzed fish emulsion [6] which require the development of microbial communities to mineralize complex organic compounds to make them plant available [7,8]. Drawbacks of organic fertilizers include variable, significantly reduced yield [9][10][11] which may be attributed to unstable microbial activity, difficulty supplying the proper proportion of nutrients, high pH as well as the development of biofilm in the organically fertilized hydroponic reservoirs [12]. Regarding biofilm, it is believed that the suspended organic matter which can develop on plant roots can also clog pumps/recirculation lines, reduce oxygen and nutrient uptake by roots and deplete nutrient solution oxygen levels [13][14][15].…”

Hydroponic production typically uses conventional fertilizers, but information is lacking on the use of organic hydroponic fertilizers. Development of microbial communities and biofilm that can reduce dissolved oxygen availability is a difficulty with organic hydroponics. One potential solution is the use of hydrogen peroxide (H2O2) which can reduce microbial populations and decompose to form oxygen. However, information is lacking on the impact of hydrogen peroxide on hydroponic crop performance. The aim of this study was to determine the effects of H2O2 concentrations in deep water culture hydroponics by assessing how it affects plant size and yield in lettuce (Lactuca sativa L.) “Rouxai”. In this experiment, three H2O2 treatments, namely the application of 0, 37.5 or 75 mg/L H2O2 to 4 L aerated hydroponic containers with either conventional or organic fertilizer, were compared. The containers had either fish-based organic fertilizer (4-4-1, N-P2O5-K2O) or inorganic mineral based conventional nutrient solution (21-5-20, N-P2O5-K2O), both applied at 150 mg/L N. Three replicates of each H2O2 treatment–fertilizer combination were prepared resulting in a total of eighteen mini hydroponic containers each with one head of lettuce. There were two growth cycles: fall 2018 and spring 2019. When added to conventional fertilizers, both 37.5 mg/L and 75 mg/L of H2O2 led to stunted growth or death of lettuce plants. However, when 37.5 mg/L of H2O2 was applied to organic fertilizers, the lettuce yield nearly matched that of the conventionally fertilized control, demonstrating that the application of H2O2 has the potential to make organic hydroponic fertilization a more viable method in the future.

“…But in contrast, Wortman et al (2016) found that strawberry yield was increased 15% more in synthetic nutrient solution than the bio-based, liquid nutrient source and vermicompost mixed with soilless media. Tikasz et al (2019) reported that Lettuce grown in a compost tea extracted from the animal manures produced higher above ground dry mass compared to the commercialy avialble Hoagland solution, but, the success depnds on the careful monitoring of NO3−, NH4+, Ca, Mg, Mn, and Na. Liquid organic fertilizers produced from waste molasses, distillery slop and sugarcane leaves produced similar growth and yield as synthetic fertilizer solution of Green Cos Lettuce (Lactuca sativa var.…”

Purpose: Macro and micronutrients rich vegetable and fish wastes are generated hugely in Sri Lanka, but not recycled properly into valuable byproducts. It is a serious problem and needs to be managed to make environment free from pollution. Extraction of nutrients from organic wastes can be used as liquid fertilizers for hydroponic crop production even in congested urban cities.Research Method: Organic hydroponic medium using vegetable waste extracts (M2), fish emulsion (M3), vermi tea (M4), the mixture of M2+M3+M4, and Albert's solution (M1-control) were prepared and tested on Spinach. The experimental setup was arranged in a CRD with four replicates. The nutritional qualities of formulated liquid fertilizers (N, P, K, Ca, Na), pH, EC, spinach growth parameters such as plant height, number of leaves per plant, leaf area, root length, weight (Fresh /Dry) were measured eight weeks after planting and subjected to ANOVA using SAS 9.1. Tukey's HSD multiple comparison test to identify the best treatment combination at P <0.05. Findings:The results revealed that the amount of each N, P, K, Na, and Ca was significantly different between treatments (P <0.05). The highest quantity of each N (11.1mg/L), P (37.99mg/L), and K (145,5 mmol/L) was detected in M2. Whereas, Na and Ca quantities were highly significant in M4 with the values of 208.7 and 96.2 mmol/L, respectively. Plant height and root length in M1, M2 and M3 were significantly higher than those of other treatments. Fresh and dry weights were also significantly higher in M3, M1 and M2 treatments when compared with other treatments. The highest leaf number and leaf area were also recorded in M3 treatment after 8 weeks of planting. Originality/ Value:This study shows that fish emulsion solution is found to be more promising and both fish emulsion and vegetable waste hydrophonics medium can be used as alternatives to Albert's solution.

“…Therefore, bioponics presents several challenges as it involves a living organic environment that conventional hydroponics do not have to deal with. The management of physicochemical parameters such as pH and electroconductivity can differ and be more complex than in conventional hydroponics [32,34]. Furthermore, the major challenge is to provide a satisfactory nutrient solution for plants, containing all the essential nutrients in adequate quantities, and free of phytotoxic substances [2,35].…”

“…However, the biochemical processes involved in their manufacturing and the original organic materials from which they are derived are not explicit. Various studies have explored methods of producing nutrient solutions from organic sources and compared them with their efficiency on plants [21,34,40,41]. These studies are of interest, as they show that one can implement bioponics in any context, using local organic waste.…”

Hydroponics is a soilless cultivation technique in which plants are grown in a nutrient solution typically made from mineral fertilizers. This alternative to soil farming can be advantageous in terms of nutrient and water use efficiency, plant pest management, and space use. However, developing methods to produce nutrient solutions based on local organic materials is crucial to include hydroponics within a perspective of sustainability. They would also allow hydroponics to be developed in any context, even in remote areas or regions that do not have access to commercial fertilizers. This emerging organic form of hydroponics, which can be qualified as “bioponics”, typically recycles organic waste into a nutrient-rich solution that can be used for plant growth. Many methods have been developed and tested in the past three decades, leading to greatly heterogenous results in terms of plant yield and quality. This review describes the main organic materials used to produce nutrient solutions and characterizes and categorizes the different types of methods. Four main categories emerged: a “tea”-type method, an aerobic microbial degradation method, an anaerobic digestion method, and a combined anaerobic-aerobic degradation method. The advantages and drawbacks of each technique are discussed, as well as potential lines of improvement. This aims at better understanding the links between agronomic results and the main biochemical processes involved during the production, as well as discussing the most suitable method for certain plants and/or contexts.
